Hi,
I'm using iPython and I've run into an occasional problem that I don't
understand. Here is what I'm seeing:
>>aa=range(0,10)
>>bb=aa
>>print aa
[0,1,2,3,4,5,6,7,8,9]
>>print bb
[0,1,2,3,4,5,6,7,8,9]
>> # okay, everything allright at this point
>>bb[5]=0 #change bb
>>print aa
[0,1,2,3,4,0,6,7,8,9] #aa has changed!!!
>>print bb
[0,1,2,3,4,0,6,7,8,9]
So the problem is that when I change bb, aa also changes even though I don't
want it to. Is this supposed to happen? If it is can someone explain to me
why this is a good thing? and finally, can someone give me some advice on how
to avoid or work-around this problem.
Thanks,
Keith
